Springvale Vineyard is a place of abundance and flavour. This should come as no surprise since Grosset's exhaustive research into viticultural potential and his meticulous care with the choice of earth itself was as geologically sophisticated and acute then as it is now. Dark grey slate and slaty siltstone of the Mintaro Shale, about 750 to 800 million years old, underlie the area. The rich red soil over limestone produces sturdy vines, big berries, chunky bunches and a lime green fruit. In some ways, these characteristics of soil and vines preview the nature of the wine that comes from this vineyard, dry with a mineral edge, savoury, yet with a noticeable fullness and richness and pronounced Riesling fruit flavour.
